IMO it was my hardware on the first tries. Not sure what your problem was, but after digging around I found something that loosely indicated that my hardware was too old or something - it didn’t play well with the onboard graphics or similar. But the second hardware set I tried it on was far newer, and after all the installation was complete I got a black screen. Every time. No matter which guide I used, no matter what dependencies I thought might be missing or whatever I tried to get it working. A hair pulling experience indeed.
